APPARATUS FOR ATOMIZING PETROLEUM-OIL FOR VAPOR FUEL.

SPECIFICATION forming part of Letters Patent No. 512,170, dated January 2, 1894.

Application filed January 22, 1891. Serial No. 378,654:- (No model.)

To aZZ whom it may concern.-

Be it known that we, EVAN A. EDWARDS and JACKSON DE NEAL, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in Apparatus for Atomizing Petroleum-Oil for Vapor Fuel; and we do hereby declare that the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification.

Our invention relates to an apparatus for atomizing petroleum oil for vapor fuel, and has especial relation to the treatment of the oil for use in combustion under boilers and in blast, puddling, or cupola furnaces, forges or heaters for warming buildings.

The object of the invention is to provide means for atomizing the oil by means of an air blast and then forcing the commingled atomized oil and atmospheric air into the combustion chamber in a vaporous condition.

The invention consists in the details of construction and combination of the various parts all of which will be described and claimed.

Figure 1 is a longitudinal sectional elevation of a boiler setting with the boiler shown in full lines, and a side elevation of the air atomizer attached at the fuel opening of the furnace. Fig. 2 is alongitudinal vertical section through the center of the atomizer. Fig. 3 is an end view of the atomizer. Fig. 4 is a detached view, showing the damper casing and damper.

The shell or casing of the apparatus consists of a series of tubular telescoping sections 1, 2, 3, &c., leading to the combustion chamber 4, to a blower or fan (not shown), whereby there may be a continuous blast of air delivered from the blower or fan to the combustion chamber. This blast maybe regulated to any desired volume by means of a damper 5 arranged in the shell.

6, designates a jet or spray pipe arranged within the shell, and connected with an oil supply pipe 7 leading to a source of supply. The jet or spray device 6 comprises one or more coils 8 of pipe arranged concentrically of the shell, the number of coils being determined by the amount of heat required or fuel to be fed. When more than one coil is used they are connected by a pipe 9 tapped into each, as shown in Figs. 2, 8 and 4.

Ooils 8 are formed with a number of minute perforations 10 preferably upon the side of the pipe next to the combustion chamber, as shown in full lines, Figs. 2. and 3.

We will now describe the operation of atomizing the oil,incorporating air therewith to support combustion, and feeding the vaporous fuel to the combustion chamber. The blower being put in operation and damper 5 adjusted to permit a blast of the desired volume to the spray, pipe or pipes S, cock 11 of pipe 7 is turned admitting oil to the jet or spray pipe or pipes 8, causing it to issue from the minute perforations 10, when the blast of air strikes the same with the elfect of cansing the oil to be carried forward in the form of spray, and to intimately co-mingle and saturate the air, whereby a vaporous fuel is formed and projected into the combustion chamber, where it is ignited by a lighted match.

In practice we may make our apparatus of different sizes to suit the purposes for which they are intended, and we may use but one jet as a spray pipe, or we may employ a series of such pipes.

What We claim is- 1. The combination with a series of articulated tubular sections of a blowing apparatus located at one end of the same, and adapted to force a current of air through the sections into a combustion chamber with which the apparatus is connected, and an oil feed pipe arranged transversely of the section adjacent to the combustion chamber, said pipe having a series of concentric coils provided with perforations for the escape of oil.

our own we hereby affix our signatures in presence of two witnesses.
